Abstract: Design parameters for chlorination facilities have been defined. The present in-use standards for these parameters have been presented in tabular form. Several contradictions intrinsic in these standards are explained. An innovative site-specific approach to these standards is presented. This design has been incorporated into the domestic wastewater facilities that have been constructed for the city of Woodland, California. In particular, these facilities include a unique method of removing solids from the detention basin. This design approach may have application to chlorination facilities currently being designed.
